The 2 patches drop constaints on the dc1sw regulator for 2 A31s tablets. I checked with Maxime and he said to send them directly to you. The issue was first brought up and fixed for A23/A33 Q8 tablets in commit dcf5341f0150 ("ARM: dts: sun8i-q8-common: Do not set constraints on dc1sw regulator"). It was brought up again yesterday on IRC, and I realized that 2 sun6i A31s tablet DTS files also had this setting. The setting causes PMIC regulator registration to fail, and since among other things, mmc depends on the regulators, the system will likely hang. There seems to be a fix for this queued up for 4.7: commit 45389c47526d ("regulator: core: Add early supply resolution for regulators") in the regulator "supply" topic branch. So we should be able to revert these fixes in 4.7.
